GMA GX3 ExtremeBlast Garnet Abrasive

Sku: P-GX3

The GMA GX3 ExtremeBlast Garnet Abrasive (P-GX3) is designed for the toughest blasting challenges. This premium abrasive achieves a uniform surface profile of 3.5 - 4.5 mil, making it ideal for TSA preparation, coatings for extreme conditions, and preparing critical components. Its unique blend of alluvial and rock garnets not only removes high build coatings but is also effective against pliable and flexible coatings including coal tar, inner liners, and certain marine coatings. With a blasting rate of up to 280 ft²/hr and a consumption rate as low as 2.5 - 3.5 lb/ft², this abrasive is highly efficient and economical. It is particularly suitable for heavy-duty applications such as offshore platform decking, tanks, piping, pressure vessels, ship hulls, and ballast tanks. Its low to medium dust factor ensures cleaner operations and minimal environmental impact. GMA GX3 is one of the coarser grades in the GMA Garnet range, perfect for removing the thickest coatings of 30+ mils and capable of handling flexible or rubberized coatings due to the sharpness of rock garnet. Available through BlastOne across the USA, this abrasive is part of a range of grades to suit every blasting challenge. The consistency in size and cleanliness is guaranteed by GMA's ISO Quality Management System.
